Imohagh, collective name of the Tuaregs of the north central Sahara, comprising the eastern Azjars and the western Ahaggars, who were formerly united under the rule of the Imanetn Sultans, but who, since the middle of the 17th century, have been constituted in two separate and independent confederacies. Imohagh is radically the same word as Imoshagh (q.v.). (J. Richardson, A Mission to Central Africa, 1855; F. Bernard, Quatre Mois dans le Sahara, 1881.)
